Quality of life assessment in a weight loss intervention.

This study evaluated whether there was a difference in quality of life scores at the end of an intervention that evaluated the effect of leucine supplementation and calorie-restricted diet over a 12-week period in mid-life overweight and obese women. At baseline and conclusion of this intervention, participants were asked to complete a quality of life questionnaire, “Quality of Life, Enjoyment, and Satisfaction Questionnaire Short Form” (Q-LES-Q-SF) and rank answers from 1-5. Of those participants that successfully lost weight during the intervention, QoL scores improved from an average of 71% to 79%. Our findings show that weight loss and quality of life can be directly associated, and purposeful weight loss can improve overall quality of life.
